Spire of Ascension, Floor 78.
"These familiar corridors… these familiar walls made out of mithril and adamantine…"
Looking around him, Rio could already sense significant similarities.
[Ding! You have entered the Spire of Ascension!]
[Ding! Your destiny intertwines with the summoner of the Spire of Ascension!]
[Ding! You must reach Floor 0 to leave!]
'My destiny intersects with someone? No… It's perhaps the strings of destiny attached to this body and the original Rio, not the actual me…'
Although his soul has entered this world, it doesn't belong here and is a foreign object after all; the rules of this world and the strings of destiny in this world can't govern over it.
For them, he's completely nonexistent.
